Applications And Types Of Dna Testing

DNA tests are one of the most multi-functional testing procedures in the medical field

Some of the most common domains where DNA tests are widely used are:

Forensic DNA Tests

DNA tests are highly helpful in solving many criminal cases. A criminal is very likely to leave some of his/her body matter containing genetic information, like hair, fingerprints, blood droplets, etc, on the crime scene which can be tested and used for chalking out the suspects. Many murder and sexual assault perpetrators have been found and punished this way. Contrarily, the test has also served to exonerate the accused based on DNA evidence of them being innocent.

Paternity DNA Test Paternity dna test The need to determine the biological father of a child may arise due to an array of reasons ranging from custody, making affidavits, prenatal determination, to alimony issues. The test is often asked for, in many lawsuits on family disputes like these.

They are done to determine the biological parents of a child and provide a dependable proof of the same. The adopting party can rightfully ask for it before adopting a child.

Immigration DNA Tests Immigration DNA Tests To get a permanent visa of a country, one must establish a documented proof of relationship between the petitioner and the referenced person. In case it cannot be produced, a DNA test is used as the second best alternative.

Property Inheritance Issues Paternity, maternity, and sibling DNA tests are used for solving many a dispute on property inheritance. This is most common in the case of extended families and adopted children.

Genetics Based Diagnosis Many diseases are linked to inherent genes and genetic mutations. A DNA test can help determine your propensity of developing such diseases as carcinoma, cystic fibrosis, hemophilia, and many others. This way you can take the necessary preventive measures and save yourself from the maladies.

DNA Based Identification of a Person A missing persons investigations can be based on genetic identification through the availability of DNA records in DNA banks. In case the record is not available, the DNA of a close blood relative can be used to aid in investigations. In those mutilated from a severe injury, DNA samples can be used for identification.

Fortunately, the development in DNA technology and the several uses of the DNA test have made it highly accessible. You can now get a cheap DNA test done by an AABB accredited laboratory for any of the purposes mentioned above.
